Today, I visited Pixar's website. I had been doing a lot of work on Mushroom Kingdom Adventure, and have been doing a lot of research into numerous graphical areas, so this was one of my usual stops for general information. While looking into the RenderMan® software, I noticed the price had been dropped and a slide passed by which was titled "Ooohh! ... Free at last!", and stated that RenderMan® will be free in the near future for non-commercial purposes.

Dr. Ed Catmull says that the team will not be limiting the free version of the software in any way, but users must agree to use it for non-commercial purposes only.
